Abstract
The gas fraction of a multiphase fluid is determined using `on-line` statistical methods and then using that fraction to compute the correct water fraction. The gas fraction (Xg) is detected by using the standard deviation of the raw phase (Pstd), maximum phase in the sampling interval (Pmax), average phase (Pavg) or standard deviation of attenuation (Astd) data and maximum attenuation in the sampling interval (Amax), or average attenuation (Aavg) from streams flowing in the water fraction monitor sensor cell where the conditions are determined.
